Used in the outlet connections of floor drain bodies, or the inside of floor drain strainers to seal the opening to prevent odors, sewer gases, and insects from entering up through the floor drain grate. The Green Drain’s four flexible silicone sealing ribs ensure easy installation into openings that have variations in size. The Green Drain will open to allow drainage and close when there is no water flow. The Green Drain can be used in either new construction or retro-fit applications where trap primers were never installed.

Prevents the following from entering through the top of floor drains:
Odors and sewer/radon gases
Insects and harmful pathogen spread
